BOBBIN OR COP WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 457,846, dated August18, 1891.

Application filed March 26, 1891- Serial No. 386,548. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN T. BYRNE, a citizen of the United States,residing at Manayunk, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in Bobbin orCop \Vinding Machines, of which the following is a specification.

Myinvention relates to machines for winding weft-yarn on shuttle bobbinsor cops of a class that are wound cone-shaped.

The object of my improvement is, in winding the yarn, to secure auniform tension on the small and large part of the bobbin or cop withoutfriction or drag on the yarn, swift, or spool.

The invention consists in the combination and arrangement, with thetraverse mechanism and an automatically-operated beltshifter, of twodriving pulleys, a counter-shaft, and four spur gear-wheels, asillustrated in the accompanying drawings, in which Figure 1 is a frontelevation of one end of a winding-machine embodying my invention. Fig. 2is a sectional elevation of Fig. 1. Fig. 3 is a sectional view of thedriving pulleys, shafts, and gear-wheels. Fig. 4 is a view of thebelt-shifter. Fig. 5 is a view of the cam and shifter-bar. Fig. 6 is aview of the beltshifter bracket.

Similar letters referto similar parts throughout the several views.

Figs. 1 and 2 show a section of a machineframe of general constructionfor winding yarn on bobbins or cops from hanks of yarn; and as I make noclaim to the general construction of the machine I will confine mydescription to that part which I claim as my invention and such parts asnecessarily co-operate with them to produce the result specified.

A represents the drum-shaft; B, the cop spindle; C, the cop; D, the hankof yarn; E, the Swifts; F, the traverse-bar; G, the traverse cam-shaft;H, the traverse-cam; J J the driving-pulleys; K, the belt-shifter; L,thebeltshifter bar; M, the belt-shifter cam; N, the counter-shaft, and PP P the gearwvheels.

The pulley J is fast on the shaft A, and pulley J is secured on orintegral with the hub of wheel P. This pulley and wheel run loose onshaft A, said wheel gearing into wheel P fast on shaft N, which shaftalso has fast on it wheel P This wheel P gears into Wheel P fast onshaft A, the wheels P and P being of one size, the wheels P and P3 beingalso of one size, but smaller than the wheels P and P 011 the shaft G, Ifasten a cam M. This cam may be heart-shaped, as shown in the drawings,or it may be a round eccentric-cam. The cam M operates the bar L, whichbar is connected to the belt-shifter K, which beltshifter works on astud fixed to bracket R.

In place of a cam the bar L may be operated by a crank placed on theshaft G.

The difference in size and number of teeth in wheels P, P P, and P isabout in the proportion of fifty to sixtythat is, wheels P and P havesixty teeth,and wheels P and P have fifty teeth.

It is to be understood that I do not confine myself to the sizeandnumber of teeth in the wheels, as that will be governed by the size ofthe cone on the bobbin.

The operations of my improvement are as follows: The cam M is set on theshaft G, so that when the yarn is being Wound on the small part of thecone it will have elevated the bar L, which being connected to thebeltshifter K, will shift the belt on the pulley J when the intermediategear-wheels will drive the drum-shaft A at an increased speed from thatwhen driven by the pulley J. This increased speed will rotate thespindle B and cop C faster than when the yarn is being wound on thelarge part of the cone, and as the shaft G revolves to move'the traversethe cam M will shift the belt to pulley J, and this being fastened toshaft A, will be the driver, and drive the spindles and cops slower thanwhen the pulley J is the driver; and the yarn will be drawn from thehank at one uniformspeed, winding on the small or large part of thebobbin with the same tension and without drag or friction on the swiftor spool.

The drawings show the yarn as being wound from hanks placed on swifts,but it is obvi-. ous that the yarn may be wound from spools.

Having as above fully described my invention and the best manner ofusing the same, what I claim as my invention is- In a b0bbin-windingframe, the combina- P loosely and the Wheel P fixedly mounted tion, witha main drivingshafb, a fast and on the main shaft, substantially asshown and 1e loose pulley thereon, a belfrshifter, a traverse mechanism,and connections between the said described.
